Hearing apparatus with a moveable charging contact

Abstract

A hearing apparatus includes a charging contact being movable relative to an accumulator and being electrically conductively connected to the accumulator in a first position and less effectively conductively connected thereto in a second position. A spring-elastic element engages with the charging contact in order to push the charging contact into the second position with a predetermined force, so that the charging contact can only be pushed into the first position by overcoming the predetermined force. As a result, the charging contact configuration obtains a switching function, so that electro-corrosion on the charging contacts can be prevented. Therefore, charging an accumulator of a hearing apparatus and in particular of a hearing device using a direct conductive contact is possible, with zero potential of the charging contacts which are accessible from the outside being ensured during normal operation of the hearing apparatus.

1. A hearing apparatus, comprising:
 a signal processing unit for processing an input signal to form a sound output signal; 
 an accumulator for supplying power to said signal processing unit; 
 a charging contact for feeding electrical energy into said accumulator, said charging contact being movable relative to said accumulator between a first position having said charging contact electrically conductively connected to said accumulator and a second position having said charging contact less effectively conductively connected or not connected to said accumulator; and 
 a spring-elastic element having a rubber sleeve engaging and surrounding said charging contact for pushing said charging contact into said second position with a predetermined force and permitting said charging contact to be pushed into said first position only by overcoming said predetermined force. 
 
     
     
       2. The hearing apparatus according to  claim 1 , which further comprises a battery spring through which said charging contact in said first position contacts said accumulator.
